The Reykjavík-centred event, Iceland's longest-running festival, will be turning 20 this year in style - Cashmere Cat, Julian Casablancas-featuring project The Voidz, Bedouine, Snail Mail, Smerz, Husky Loops, and many more are also joining the lineup, which already features the likes of Superorganism, Soccer Mommy, and Girl Ray.

As usual there will be an eclectic mixture of homegrown talent and overseas names, with Mammút, Vök, GKR, Young Karin, Pink Street Boys, and Axel Flóvent among the Icelandic artists added in the latest wave.
